1. Middle C is 261.6 Hz. Find the following:
a. the next two C's above this note (one and two octaves above)
b. the C one octave below middle C
c. C#, which is one semi-tone (or piano key or guitar fret) above C
d. D, which is two semi-tones above C
e. The wavelength of middle C, if the speed of sound is 340 m/s
2. Consider an organ pipe 0.7-m long. Find the following:
a. the wavelengths of the first 3 harmonics
b. the frequencies of the first 3 harmonics (speed of sound is 340 m/s)
c. the wave shapes associated with the first 3 harmonics - draw them
d. What would happen if you cap this pipe on one end?
